Overview
MAXON APX® Natural Gas Burners are packaged nozzle mixing line burners designed for fresh or low temperature re-circulated air heating applications. The APX® Industrial Burner is a value engineered design utilizing a single aluminum extrusion for both its air and fuel manifolds. Its single-piece, joint-less body design provides standard straight gas burners up to 40 feet (12 meters), H-shaped burners, and grid shaped burners engineered to your specification. APX® burner construction provides years of maintenance free operation and lower cost of ownership than any other alternative.
Features & Benefits:
Features & Benefits:
- Nozzle-mixing line burner for use with low pressure natural gas, propane and butane
- Eliminates leakage with its single-piece, aluminum extrusion body design
